  • Page 11: Getting Started

    Getting Started...

  • Page 13: Using The Usb Interface

    Getting Started Your power supply has a USB 2.0 high-speed device port to control the power supply using the USBTMC protocol. The USBTMC protocol allows USB devices to communicate using IEEE-488.2 style messages. If you have a G-version, you can also remotely communicate between your power supply and PC over GPIB.

  • Page 14: Command Timing

    Getting Started The power supply is now set up for bidirectional communication with your controller. Command Timing The average time it takes to both send and receive every command is approximately 20 ms. In the case of more complex commands, more time may be required to complete transmission.

  • Page 15: Command Syntax

    Command Syntax You can control the power supply through the USB interface or the GPIB interface (G-version instruments only) using commands and queries. This section describes the syntax these commands and queries use and the conventions the power supply uses to process them. The commands and queries themselves are listed by group and alphabetically.
  • Page 16 Command Syntax Table 2-2: Command message elements Symbol Meaning <Header> The basic command name. If the header ends with a question mark, the command is a query. The header may begin with a colon (:) character; if the command is concatenated with other commands the beginning colon is required.

  • Page 17: Command Entry

    Command Syntax You can specify a query command at any level within the command tree unless otherwise noted. These branch queries return information about all the mnemonics below the specified branch or level. Query Responses When a query is sent to the power supply, only the values are returned. When the returned value is a mnemonic, it is noted in abbreviated format, as shown in the following table.
  • Page 18 Command Syntax You can create commands and queries from these subsystem hierarchy trees. Commands specify actions for the instrument to perform. Queries return measurement data and information about parameter settings. Message Terminators This manual uses the term <EOM> (End of message) to represent a message terminator.
  • Page 19 Command Syntax Abbreviating Commands, You can abbreviate most SCPI commands, queries, and parameters to an accepted short form. This manual shows these commands as a combination of upper and Queries, and Parameters lower case letters. The upper case letters indicate the accepted short form of a command, as shown in the following figure.
  • Page 20 Command Syntax General Rules for Using The following are three general rules for using SCPI commands, queries, and parameters: SCPI Commands You can use single (‘ ’) or double (“ ”) quotation marks for quoted strings, but you cannot use both types of quotation marks for the same string. correct “This string uses quotation marks correctly.”...

  • Page 21: Command Groups

    Command Groups This manual lists the power supply commands in two ways. First, it presents them by functional groups. Then, it lists them alphabetically. The functional group list starts below. The alphabetical list provides detail on each command. (See page 2-13.) The power supply interface conforms to Keithley standard codes and formats except where noted.
